Measuring the Impact of Bilingualism on Executive Functioning Via Inhibitory Control Abilities in Autistic Children

The impact of educational and medical systems on autistic children from multilingual American homes: A systematic review

LAY ABSTRACT

Research has found that autistic children can navigate multilingual schools and communities without harming their language skills or school success. However, they may encounter specific challenges within the United States, where educational and healthcare systems are insufficiently equipped to meet their needs. This review examined 46 US-based studies on the topic and findings reveal persistent deficit-based ideas about multilingualism and autism (e.g., professionals recommending that autistic students only speak and learn in English) accompanied by patterns of unequal identification of autism among multilingual children. These findings highlight issues of disproportionality and inadequate access to educational and healthcare resources. However, recent studies indicate that incorporating a child's native language in education not only enhances learning and behavioral outcomes but also boosts cognitive functions like problem-solving and planning. Taken as a whole, current research suggests that intentionally addressing linguistic diversity will allow educational and medical systems to better serve autistic children.

It's our job to bridge the gap: Perspectives of bilingual autism providers on heritage language care

LAY ABSTRACT

In the United States, many people have heritage languages they speak in their homes other than English, such as Chinese or Spanish. Autistic children whose families speak different languages could benefit from support and teaching in their heritage languages. Still, caregivers have reported that it is challenging to do so. Many autism professionals make suggestions that are not based on research. To date, researchers have not examined the perspectives of the small group of bilingual professionals in the United States who provide bilingual support for autistic children. Therefore, this study explored how bilingual autism providers in the United States talked about their work, bilingualism, and the impacts their bilingual work has on autistic children and families. The bilingual providers in this study reported many positive outcomes for autistic children when they can learn and use their heritage languages and some negative outcomes when providers cannot communicate in the same language. Recommendations from this study highlight the need to recruit more bilingual providers in the field of autism.

Bilingualism and second-order theory of mind development in autistic children over time: Longitudinal relations with language, executive functions, and intelligence

Theory of Mind has long been studied as a core weakness in autism spectrum disorder due to its relationship with social reciprocity, while bilingualism has been shown to compensate for autistic individuals' mentalizing weaknesses. However, our knowledge of the Theory of Mind developmental trajectories of bilingual and monolingual autistic children, as well as of the factors related to Theory of Mind development in autism spectrum disorder is still limited. The current study has examined first- and second-order Theory of Mind skills in 21 monolingual and 21 bilingual autistic children longitudinally across three time points, specifically at ages 6, 9, and 12, and also investigated associations between Theory of Mind trajectories and trajectories of the children's language, intelligence and executive function skills. The results reveal that bilingual autistic children outperformed their monolingual peers in second-order Theory of Mind at ages 9 and 12, and that intelligence and, especially, expressive vocabulary skills played a pivotal role in advancing bilingual autistic children's second-order Theory of Mind development. On the other hand, monolingual autistic children only managed to capitalize on their language and intelligence resources at age 12. The findings highlight the importance of investigating bilingualism effects on autistic children's advanced cognitive abilities longitudinally.

I'm One Person, I Can't Be Everywhere: Challenges and Needs of Bilingual Behavior Analysts

Autistic children from Spanish-speaking homes are part of a growing group of children at the intersection of multiple marginalized identities. Research suggests a "bilingual advantage" exists, similar to that experienced by neurotypical bilingual children, and autistic adults report positive social outcomes due to being bilingual. However, much less is known about providers' experiences who play a crucial role in whether families can maintain their heritage language(s) with their children. This exploratory qualitative study examined ethical challenges and needs of U.S.-based bilingual behavior analysts who provide home-based support for autistic children from Spanish-speaking homes. This study was informed by a demographic questionnaire and semi-structured interviews with participants (N = 14) across the United States. Participants' experiences were analyzed thematically. Findings included major themes and subthemes including challenging ethical experiences and behavior analysts' needs to provide high quality services. Implications are presented across the organizational, provider, and research and higher education levels.

Bilingualism Predicts Affective Theory of Mind in Autistic Adults

PURPOSE

This study examined the impact of bilingualism on affective theory of mind (ToM) and social prioritization (SP) among autistic adults compared to neurotypical comparison participants.

METHOD

Fifty-two (25 autistic, 27 neurotypical) adult participants (ages 21-35 years) with varying second language (L2) experience, ranging from monolingual to bilingual, completed an affective ToM task. A subset of this sample also completed a dynamic eye-tracking task designed to capture differences in time spent looking at social aspects of a scene (SP). Four language groups were compared on task performance (monolingual autism and neurotypical, bilingual autism and neurotypical), followed by analyses examining the contribution of L2 experience, autism characteristics, and social face prioritization on affective ToM, controlling for verbal IQ. Finally, we conducted an analysis to identify the contribution of SP on affective ToM when moderated by autism status and L2 experience, controlling for verbal IQ.

RESULTS

The monolingual autism group performed significantly worse than the other three groups (bilingual autism, monolingual neurotypical, and bilingual neurotypical) on the affective ToM task; however, there were no significant differences between the bilingual autism group compared to the monolingual and bilingual neurotypical groups. For autistic individuals, affective ToM capabilities were positively associated with both verbal IQ and L2 experience but did not relate to autism characteristics or SP during eye tracking. Neurotypical participants showed greater SP during the eye-tracking task, and SP did not relate to L2 or autism characteristics for autistic individuals. SP and verbal IQ predicted affective ToM performance across autism and neurotypical groups, but this relationship was moderated by L2 experience; SP more strongly predicted affective ToM performance among participants with lower L2 experience (e.g., monolingual) and had less of an impact for those with higher L2 experience.

CONCLUSION

This study provides support for a bilingual advantage in affective ToM for autistic individuals.

Putting the Spotlight Back Onto the Flanker Task in Autism: Autistic Adults Show Increased Interference from Foils Compared with Non-autistic Adults

Autistic people may have a less focused spotlight of spatial selective attention than non-autistic people, meaning that distracting stimuli are less effectively suppressed. Previous studies using the flanker task have supported this suggestion with observations of increased congruency effects in autistic participants. However, findings across studies have been mixed, mainly based on research in children and on response time measures, which may be influenced by differences in response strategy between autistic and non-autistic people rather than differences in selective attention. In this pre-registered study, 153 autistic and 147 non-autistic adults completed an online flanker task. The aims of this study were to test whether increased congruency effects replicate in autistic adults and to extend previous work by fitting a computational model of spatial selective attention on the flanker task to the data. Congruency effects were increased in the autistic group. The modelling revealed that the interference time from the foils was increased in the autistic group. This suggests that the activation of the foils was increased, meaning suppression was less effective for autistic participants. There were also differences in non-interference parameters between the groups. The estimate of response caution was increased in the autistic group and the estimate of perceptual efficiency was decreased. Together these findings suggest inefficient suppression, response strategy and perceptual processing all contribute to differences in performance on the flanker task between autistic and non-autistic people.

Raising bilingual autistic children in the UK: at the intersection between neurological and language diversity

Introduction

While research shows no negative effects of bilingualism on autistic children's development, due to misconceptions around both autism and bilingualism, bilingual parents and educational/clinical practitioners who advise them often express unfounded concerns that exposing autistic children to more than one language will cause confusion and developmental delays. To understand the reasons that drive these misconceptions, this study focuses on: identifying factors that impact family decisions about (not) raising autistic children bilingually; attitudes toward bilingualism expressed by the community, doctors, family members, and teachers; sources of information about bilingualism and autism available to families.

Methods

Through a mixed-method online survey, we explored these questions in 31 UK-based bilingual families with 34 autistic children (age M = 10.6 years; SD = 7.1).

Results

The families reported choosing bilingualism for their autistic child primarily so that the child can communicate with family and community members. Attitudes toward bilingualism in their networks were predominantly positive, with a large portion of individuals not having opinions possibly due to lack of information. Only about 1/3 of parents had access to information on bilingualism and autism, mostly found on the internet.

Discussion

We discuss these findings and offer future directions for research, practice, and battling stigmas around bilingualism and autism.

Early years autism and bilingualism: An interpretative phenomenological analysis of parent perceptions during lockdown

AIM

This study explores how bilingual parents of autistic children made language decisions for their families, how the event of the SARS-CoV-2 pandemic and subsequent lockdown impacted the communication environment of their households, and whether these experiences affected their language habits.

METHOD

Semi-structured interviews were conducted with five bilingual parents of autistic children who lived through lockdown in France. Data were analysed using interpretative phenomenological analysis. Demographic and background information was collected using an adapted version of the Questionnaire for Parents of Bilingual Children.

RESULTS

Participants reported conflicting advice given by a range of practitioners. Parents expressed differing beliefs about the impact of language choices on their children. Parents described active engagement with their children's home-learning as generally positive. Parents identified an increase in children's exposure to their first language during the lockdown. Parents reported an increase in children's overall communication abilities.

CONCLUSION

Parents believed that their children's positive communication development during lockdown was related to increased exposure to their first language(s), and direct involvement in their children's learning programs.

Autistic People's Access to Bilingualism and Additional Language Learning: Identifying the Barriers and Facilitators for Equal Opportunities

Bilingualism is a valuable tool that enriches and facilitates cultural, social and lived experiences for autistic and non-autistic people alike. Research consistently finds no negative effects of bilingualism and highlights the potential for positive effects across cognitive and socio-cultural domains for autistic and non-autistic children. Yet parents of autistic children remain concerned that bilingualism will cause delays in both cognitive and language development and are still frequently advised by practitioners to raise their child monolingually. Evidently, findings from research are not reflected in practice or subsequent advice, and it is essential to identify ways to ensure equal access to additional language learning. We briefly summarise the existing literature on bilingualism and autism, considering perspectives from the bilingual autistic community, and experimental research. We identify the most pertinent barriers to participation for autistic bilingual children in terms of familial, clinical and educational perspectives. We propose novel solutions to promote additional language learning and suggest changes to practice that will contribute to an evidence base for families and practitioners. This commentary makes innovative recommendations at both the individual and societal level to ensure that autistic bilingual people have equal rights and opportunities to language learning and are optimally supported in accessing them.
